group of people gathered on a beach

group of people gathered on a beach. The crowd includes people in wetsuits, some wearing swimming caps, seemingly preparing for a swimming event. There's a large inflatable arch marking the start or finish line of the event. The beach itself appears sandy, and the sky is clear and blue. Some people are standing around talking or stretching, while others are walking towards the water. The atmosphere seems relaxed and anticipatory. In the background, some buildings and possibly a port area can be seen.
